Description
Technical field
This utility model relates to a kind of buncher novel speed governing operating mechanism, particularly a kind of belt-type separation conical pulley stepless speed change device novel manual speed governing operating mechanism.
Background technology
Buncher is a kind of variable transmission, and its functional character is: in the case of input speed is constant, can realize the rotating speed consecutive variations within the specific limits of output shaft, to meet the requirement of various different operating modes in operation process of machine or production system.Belt-type separation conical pulley stepless speed change device is the main Types of buncher, basic structure and the transmission principle of belt type continuously variable transmission are essentially identical with V belt translation, when active wheel rotates, utilize the frictional force between belt (metal tape) and the cone pulley of tensioning, motion and power are delivered to driven pulley from drivewheel, and band operating position in conical pulley can be changed by operating mechanism, make the working diameter of driving and driven cone pulley can recur change, thus realize infinitely variable speeds.
Belt-type separation conical pulley stepless speed change device mode of speed regulation mainly has: adjusting center distance gear shift mode, double pulley gear shift mode, counter wheel gear shift mode, regulation belt wheel axial location realize the mode four kinds of speed change.But either adjusting center distance gear shift mode, or double pulley gear shift mode, all make use of the tensile force of band and the tensile force of spring to make band interact with belt wheel, and change band well width have adjusted the diameter of belt wheel, thus realize speed change.Being not difficult to find out, this mode of speed regulation directly results in the severe friction between band and belt wheel, thus decreases the service life of band；And so speed governing is it cannot be guaranteed that the center of two belt wheels is all the time on a centrage, it may occur however that some are eccentric, transmission efficiency can be produced impact.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of belt-type separation conical pulley stepless speed change device novel manual speed governing operating mechanism, when realizing belt-type separation cone pulley buncher speed governing by breakthrough innovative design, two centers separating cone pulleys are all the time on a centrage, transmission band and the severe friction of cone pulley wall when reducing speed governing, thus improve its transmission performance, effectively extend transmission tape lifetime, promote the buncher extensive application in machinery industry.
For achieving the above object, the technical scheme that this practicality is used is: a kind of belt-type separation conical pulley stepless speed change device novel manual speed governing operating mechanism, including push pedal one, push pedal two, female thread branch sleeve, screw rod, hands is taken turns, thrust bearing one, thrust bearing two, end clamp plate, clamping screw, push pedal is between thrust bearing one and thrust bearing two, end clamp plate connects by clamping screw and the slip cone pulley separating cone pulley are fixing, thrust bearing and push pedal are compressed by the slip cone pulley wall of end clamp plate and separation cone pulley, and power shaft is identical with the physical dimension separating cone pulley on output shaft.
Described push pedal one and push pedal two are all bolted to connection with female thread branch sleeve.
Described female thread branch sleeve and screw flight connect.
A kind of belt-type separation conical pulley stepless speed change device novel manual speed governing operating mechanism that this utility model provides, by rotating handwheel, screw rod is rotated, then inner thread sleeve axially-movable, owing to female thread two ends are rigidly connected with push rod one and push rod two, then push rod one and push rod two make constant speed, etc. the axially-movable in the same direction of displacement.Push rod one and push rod two are respectively to actively separating cone pulley and the driven separation cone pulley cone pulley that slides axially forms extruding, two cone pulleys that slide axially are moved axially, thus change the working diameter of driving and driven belt wheel simultaneously, finally change gear ratio, so realize the purpose of continuous stepless speed governing within the specific limits.
